Process models for Portland cement manufacturing


Project Description

Cement is the most ubiquitous product after drinking water, with 4.1B tons produced in 2017 alone, enough for half a ton per person per year worldwide. Its production also accounts for 5% of man-made CO2 emissions, thus any improvement to the production efficiency will have a meaningful change to our environmental impact. Critical to the production process are the calcination and the high-temperature (~1450℃) “clinkering” reaction. The former releases CO2 contained within the limestone used as raw ingredients for the cement, whereas the clinkering reaction requires significant amounts of fuel to reach the required temperature to form the “cementicious” phases.

This PhD will continue our world-leading research in this field (see cited works), focused on improving our understanding of the clinker process, both in developing new formulations and optimising existing systems. The project’s focus will be on developing the process models for the kiln, calciner, cyclones, and clinker cooler, as a general tool. The work is complementary to our recently funded Nanocem Core Project 17 and will form part of the University’s partner project to Nanocem. This means the work is led by industry needs and will work in close collaboration with industrial partners. It will also be involved in ongoing consultancy work for the design of new cement processes.

The approach will be a mixture of theoretical/computational modelling of the heat transfer, mass transfer, and thermodynamics of the system, along with experimental validation and data gathering. There is scope for the student to develop new high-temperature experimental techniques, run pilot-scale trials of new cement processes, and/or develop new computational models according to their own strengths and interests.

Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in chemical engineering, physics, chemistry, or a related field with essential knowledge of heat transfer and programming. Any background in process modelling, python, or C++ is highly desirable.
